A boy is writing a paper on childbirth
and asks his parents: "How was I born?"
His mother awkwardly answers: "The stork brought you."
"Oh," says the boy. "Well, how were you and Daddy born?"
"Oh, the stork brought us, too, and Grandpa and Grandma."
The boy begins his paper: "This report has been very difficult to write due to the fact that there hasn't been a natural childbirth in my family for three generations."
